Answer:
6x - 18
Step-by-step explanation:
3 x 6 = 18, so thats how you get the 18 in the answer
3 x 2x = 6x, which is how you get the 6x
and theres a subraction sign so we know to put a - there.
Answer:
6x - 18
Step-by-step explanation:
3(2x - 6) =
("... - 6" means that whatever we do with the 6, we have to remember that it's negative)
3(2x - 6) =
3 * 2x + 3 * (-6) =
6x + (-18) =
(if we add a negative number then it's the same as subtracting that number)
6x + (-18) = 6x - 18

in 2010, the price of a laser printer was $1599. in 2018, the price of the same type of printer had dropped to $579. find the percent of decrease. round to the nearest percent
Hi there!
nearest percentage=64%
1.Subtract starting value and final value:
[tex]1599-579=1020[/tex]
2.Divide it by the starting value:
[tex]1020*1599= 0.6378986866791744840525328330206378986[/tex]
3.Multiply the term by 100:
[tex]0.6378986866791744840525328330206378986[/tex]·[tex]100= 63.78986866791744840525328330206378986[/tex]
4.Round the term:
[tex]63.78986866791744840525328330206378986=64[/tex]
Therefore, the decrease of the total 8 years was 64%.
Answer:
64%
Step-by-step explanation:
579 is a 63.789868667917% decrease of 1599.
Percentage of decrease = |1599 - 579|/1599 = 1020/1599 = 0.63789868667917 = 63.789868667917%

what is two numbers that add to 20 and the difference is 6
13 and 7.
Steps
x + x = 20
x - x = 6
2x = 26
x = 13
x = 20 - 13
x = 7
Answer:
13 and 7
Step-by-step explanation:
We have two unknown numbers that add up to 20 and subtract to 6. The question is asking us to find out these two hidden numbers.
Let's form two equations.
x + y = 20
and
x - y = 6
Since we have a positive y and negative y, we can use the addition method to these systems of equations.
x + y = 20
x - y = 6
+-----------------
2x = 26
Now isolate x to get x.
Divide both sides by 2 :
x = 13
Now that we have x, we can plug it into the equations.
13 + y = 20
13 - y = 20
So what number will make this true. Use the backwards method :
20 - 13 = 7
Therefore, 13 and 7 are our two numbers.

Describe two methods that can be used to find the area of the composite figure.
Answer:
Reason 1: To find the area of a composite figure or other irregular-shaped figure, divide it into simple, nonoverlapping figures. Find the area of each simpler figure, and then add the areas together to find the total area of the composite figure.
Reason 2: To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together.

Can Someone help me to answer the question
Answer: X = -4
Step-by-step explanation:
90 - 5x + 62 -2x = 180
152 - 7x = 180
-7x = 28
x = -4
Check your answer by pluging in the vaule of x
90 - 5(-4)
90 + 20 = 110
62 - 2(-4)
62 + 8 = 70
110 + 70 = 180
Checks out.
Answer: 110 degrees and 70 degrees
Step-by-step explanation:
These angles are same side (of the traversal line) interior (inside the parallel lines) angles. Same side interior angles sum to 180 degrees. Add the two angles together and set them equal to 180. (90-5x) + (62-2x) = 180
Combine like terms. 90+62= 152 and -5x + -2x = -7x rewrite the equation as 152 + -7x = 180
Subtract 152 from both sides of the equation.
-7x = 28. Now isolate x by dividing both sides by -7. X= -4. Now we can substitute -4 back into the original equations. 90 -5(-4) = 90 +20 = 110 and 62 - 2(-4) = 62 + 8 = 70
We can double check our work to see if these two indeed add up to 180. 110 + 70 = 180

Step-by-step explanation: The earliest fractions were reciprocals of integers: ancient symbols representing one part of two, one part of three, one part of four, and so on.[28] The Egyptians used Egyptian fractions c. 1000 BC. About 4000 years ago, Egyptians divided with fractions using slightly different methods. They used least common multiples with unit fractions. Their methods gave the same answer as modern methods.[29] The Egyptians also had a different notation for dyadic fractions in the Akhmim Wooden Tablet and several Rhind Mathematical Papyrus problems.[citation needed]
The Greeks used unit fractions and (later) continued fractions. Followers of the Greek philosopher Pythagoras (c. 530 BC) discovered that the square root of two cannot be expressed as a fraction of integers. (This is commonly though probably erroneously ascribed to Hippasus of Metapontum, who is said to have been executed for revealing this fact.) In 150 BC Jain mathematicians in India wrote the "Sthananga Sutra", which contains work on the theory of numbers, arithmetical operations, and operations with fractions.
A modern expression of fractions known as bhinnarasi seems to have originated in India in the work of Aryabhatta (c. AD 500), Brahmagupta (c. 628), and Bhaskara (c. 1150). Their works form fractions by placing the numerators (Sanskrit: amsa) over the denominators (cheda), but without a bar between them. In Sanskrit literature, fractions were always expressed as an addition to or subtraction from an integer. The integer was written on one line and the fraction in its two parts on the next line. If the fraction was marked by a small circle or cross, it is subtracted from the integer; if no such sign appears, it is understood to be added.

F(x)=4x^2+4x-15 Write the function D in intercept form. Use this form to list the zeros of the function.
Answer:
Zeros are x = 1.5, -2.5
Step-by-step explanation:
Given function is,
F(x) = 4x² + 4x - 15
= 4(x² + x - 3.75) [Since, intercept form of a quadratic equation is the factored form of the function]
F(x) = 4(x² + 2.5x - 1.5x - 3.75)
= 4[x(x + 2.5) - 1.5(x + 2.5)]
= 4(x - 1.5)(x + 2.5)
For 'x' intercepts,
f(x) = 0
4(x - 1.5)(x + 2.5) = 0
x = 1.5, -2.5
Therefore, zeros of the given function are x = 1.5, -2.5.

The surface area of the cuboid box is S = 126 cm²
What is the surface area of cuboid?
A cuboid is defined as a three-dimensional shape, that has six rectangular faces, eight vertices and twelve edges
The total surface area of the cuboid is given by the formula
Surface Area = 2 ( LH + LW + HW )
where ,
Length of the cuboid = L
Width of the cuboid = W
Height of the cuboid = H
Given data ,
Let the surface area of cuboid be S
Length of the cuboid = L = 6 cm
Width of the cuboid = W = 5 cm
Height of the cuboid = H = 3 cm
On simplifying , we get
Surface Area = 2 ( LH + LW + HW )
S = 2 ( ( 6 x 5 ) + ( 6 x 3 ) + ( 5 x 3 ) )
S = 2 ( 30 + 18 + 15 )
S = 2 ( 63 )
S = 126 cm²
Hence , the surface area is S = 126 cm²
